Job summary

Praxy is seeking a Data Scientist to own measurement science for our advertising platform. You will design incrementality tests, build MMMs, and apply causal analysis to quantify value for advertisers, shaping bidding and optimization and influencing product direction.

Collaborate with Engineering, Product, Sales, and Customer Success to ensure measurement is statistically sound and operationally useful, communicating insights clearly in a remote-first, fast-growing setting.

Qualifications

• Bachelor's or Master's degree in Statistics, Economics, Data Science, Computer Science, or related quantitative field.
• 3–5 years of applied data science experience with a focus on marketing measurement—incrementality, MMM, attribution, or causal analysis.
• Hands‑on experience designing and analyzing experiments (A/B, geo, holdout) in a marketing or advertising context.

Responsibilities

• Design and run incrementality experiments (geo, ghost bidding, holdout, PSA) to quantify lift for advertisers.
• Build, maintain, and evolve marketing mix models (MMM) and multi-touch attribution analyses across campaigns.
• Apply causal inference methods — diff‑in‑diffs, synthetic controls, instrumental variables, propensity scoring — to questions beyond RCTs.
• Translate measurement results into clear narratives for advertisers and internal stakeholders.

Job description

The Data Scientist will own the measurement science behind Audiohook's performance audio advertising platform. You'll design and run incrementality tests, build and maintain marketing mix models, and apply causal analysis to quantify how Audiohook drives outcomes for advertisers. This role combines hands‑on modeling with the opportunity to shape how we prove value to customers, sharpen our bidding and optimization systems, and influence product direction. You'll collaborate closely with Engineering, Product, Sales, and Customer Success to ensure measurement isn't just statistically sound but operationally useful.

KEY RESPONSIBILITIES

MARKETING MEASUREMENT & CAUSAL INFERENCE

• Design and run incrementality experiments (geo, ghost bidding, holdout, PSA) that quantify Audiohook's lift for advertisers
• Build, maintain, and evolve marketing mix models (MMM) and multi-touch attribution analyses across customer campaigns
• Apply causal inference methods — difference-in-differences, synthetic controls, instrumental variables, propensity scoring — to questions that can't be answered with RCTs
• Translate measurement results into clear narratives for advertisers, internal stakeholders, and the product team

MODELING & ANALYSIS

• Partner with Engineering on the data and modeling layer that powers bidding, pacing, and optimization decisions
• Develop and validate predictive models that improve campaign performance and platform efficiency
• Instrument experiments and analyses for reproducibility, monitoring, and ongoing measurement quality

CROSS-FUNCTIONAL COLLABORATION

• Partner with Sales and Customer Success on measurement studies for priority accounts and renewals
• Partner with Product on roadmap inputs grounded in causal evidence, not just descriptive data
• Present findings to advertisers, internal teams, and leadership in clear, decision-ready formats
• Communicate clearly and proactively in a remote‑first environment

QUALIFICATIONS

REQUIRED

• Bachelor's or Master's degree in Statistics, Economics, Data Science, Computer Science, or related quantitative field
• 3–5 years of applied data science experience with a focus on marketing measurement — incrementality, MMM, attribution, or causal analysis
• Hands‑on experience designing and analyzing experiments (A/B, geo, holdout) in a marketing or advertising context
• Strong fluency in Python (pandas, statsmodels, scikit-learn, PyMC, or similar) and SQL
• Solid grounding in statistical inference, regression, and causal methods
• Ability to communicate technical results to non-technical audiences — advertisers, sales, leadership
• Excellent attention to detail and intellectual honesty about model limitations

PREFERRED

• Experience in adtech, digital advertising, or media measurement
• Experience with Bayesian methods or Bayesian MMM frameworks (e.g., PyMC-Marketing, LightweightMMM, Robyn)
• Experience working with large-scale ad event data (impressions, clicks, conversions) and modern data stacks (e.g., Iceberg, Snowflake, BigQuery)
• Experience in a startup or high‑growth company
• Comfort using AI tools to accelerate exploratory analysis, code, and write-ups while maintaining methodological rigor

WHAT WE OFFER

• Fully remote work environment
• Competitive salary and equity opportunities
• Performance bonuses
• Health, dental, and vision benefits
• Other benefits such as daily lunch stipend, monthly wifi, cell phone and subscription reimbursement, and annual hardware stipend
• Flexible PTO and remote‑friendly culture
• Bi‑annual Corporate Offsites
• Opportunity to help shape a function at a rapidly scaling tech company
